Abstract
A method of monitoring and controlling a power distribution system is provided. The power distribution system includes a plurality of circuit breakers, a plurality of node electronic units, and wherein each associated circuit breaker is electrically coupled with each respective node electronic unit. The system also includes at least one digital network, and at least one central control processing unit (CCPU) wherein each CCPU includes a first power system global information set, and each CCPU is communicatively coupled to the plurality of node electronic units. The method includes transmitting at least one digital message from each node electronic unit to each CCPU over a respective network, determining an operational state of the power distribution system from the digital message, and transmitting at least one multicast message from each CCPU to each node electronic unit such that the circuit breakers are operable from each CCPU.
